If you're an iffy flyer, like I am, and stress a lot ... give yourself 2 hrs Negril to Mobay; 2 hours for check in/immigration/security (although immi isn't an issue for Canadians now, I think) and book Club MoBay! Zoom thru Security (provided you are good!) and you're laughing! You never know when a flight to the north will be delayed and even if its not, Club Mobay is worth the USD30!
